Definitions
- the invention relates to a rotary latch pull with an open end face hollow cylindrical housing, in which non - rotatable between two by one
- the driver determines the end positions of a piston open on the same end face in the axial direction is movable, in the counteracting the action of a spring, a safety socket is displaceable, the outer end position of which is held by the housing and the radially penetrating segment is determined by the head of a Pull pin is pluggable.
- Jack trains are used to control the movement processes in injection molds have two parting planes.
- opening the injection mold after spraying the In many cases it is necessary to close the moldings first in a parting plane open, keeping locked in the other parting plane, and only when the a parting plane is sufficiently open to unlock the locked part and also to open the other parting plane.
- So-called tear-off forms are an example of use called, in which the sprue from the molding during the demolding triggers and apart from the main parting level, through which the molding from the Injection mold can emerge, a further parting plane is provided, from which the Sprue can escape.
- interlocking latches of the type mentioned at the outset which are known in their pulling and locking function and are introduced as standard parts, are used (see, for example, brochure Z 173 / ... Ratchet Pull "from Hasco-Normalien, Lüdenborg, from 10/94).
- additional space must be made available between the system bores used for tools or standards for receiving the guide elements If there is a requirement for a pair of symmetrical arrangement of the latch handles, a substantial part of the work surface is lost for their accommodation.
- the invention seeks to remedy this.
- the invention is based on the object to train a jack latch of the type mentioned so that it next to the Pull and lock function a guide function as an additional function assumes that no additional space is made available for its use must become.
- this object is achieved in that the Housing inside as a guide bush and the tension bolt outside as a guide bolt are carried out, with the guide bush and draw bolt centering.
- the round latch pull takes on an additional function. He has Guiding properties, similar to those in the tool and standard part area used guide elements.
- the installation diameter of the draw bolt and the Circular jack housing can be in tolerance and dimension Guide elements of a standard system are adapted.
- the ratchet pull according to the invention can be used in tools or standards instead of the usual Guide elements can be installed in existing system bores. Thereby there is no additional installation space, e.g. between the system holes. It is gained additional work space for the construction.
- the ratchet pull brings space-saving installation options. It is rational to install what time and Saves costs. If round latches according to the invention in existing System holes are used, a relatively high machining effort is eliminated; only minor modifications are required. Adapters are available for attachment and screw and tuning elements are available.
- the housing has a paragraph or smooth outer diameter without stop diameter. This continues to improve the adaptation to the existing system bores for tools or standard parts.
- an injection mold with three axially to each other movable, partially constructed from several releasably braced plates Shaped parts are provided, which against each other by means of sliding guide bolts and sockets are guided, the sliding guide pins and bushings in the plates of all Shaped parts are arranged in the axial direction penetrating system holes is characterized in that at least two mirror-symmetrically arranged System bores of one of the housings and the guide pin after the Invention are enforced.
- the round latch pull selected as an exemplary embodiment has a pull bolt 1 and the draw bolt 1 receiving housing 2.
- the housing 2 is hollow cylindrical executed and open on the end facing the draw bolt 1.
- Housing 2 is a piston 3 in which is open on the same end face against rotation Movable in the axial direction.
- the housing 2 is used to prevent rotation provided with diametrically opposed longitudinal slots in which one with the Piston 3 is guided via a threaded pin 7 connected driver 6.
- piston 3 is a securing bushing 4 slidable.
- the outer end position of the locking bush 4 is by one of the Housing 2 held and the piston 3 radially penetrating segment 5 determined.
- the facing head of the draw bolt 1 can be inserted through the segment 5.
- the injection mold chosen as an embodiment consists of three in the axial direction movable mold parts 10, 20 and 30.
- the first outer mold part 10 composed of plates 11, 12, 13 and 14, the third outer molded part 30 from two plates 31, 32.
- the parting line 40 is provided around this To control movement, two ratchet pulls are provided, the diametrical are fastened opposite each other at the corners of the injection mold in system bores. In the two system holes provided in the other corners Guide elements provided.
- the guide bushings 15, 16, 25 are of a guide pin 37 penetrates, which is fastened in the molded part 30.
- Individual plates are through Bolts 61 connected together.
- the tension bolt 1 is in the molded part 10 by means of a screw bolt 62; the housing 2 on the molded part 30 by means of a Bolt 63 attached.
